Halogen bulbs contain halogen gas that re-deposits tungsten back onto the filament, allowing the filament to be reused and making halogen bulbs last longer than incandescent bulbs. However, halogen bulbs burn much hotter and brighter than traditional incandescent bulbs. Metal halide lamps are commonly used for streetlights and stadium lights because they are very bright and efficient, producing white light that renders colors accurately. High pressure sodium lamps are the most common type of streetlight due to their efficiency and low maintenance needs, though they produce a yellow-orange glow. Neon lamps contain neon gas and produce a distinct orange glow when electricity is passed through, making them suitable for

Lighting and Appliances
Anything that draws electrical power is referred to as a load. Part of weatherizing a home includes minimizing the loads in the home in order to lower energy bills and maximize energy efficiency.
Artificial Lighting
Artificial lighting is provided by electricity, fixtures, and bulbs. Artificial lighting is a big contributor to high energy costs. It can contribute as much as 50 percent of the total energy costs of a home.
Lynn Clement of Focus on Energy once said, “If every American household replaces light bulbs in their five most frequently used fixtures with ENERGY STAR compact fluorescent bulbs, we could save more than $8 billion in annual energy costs and prevent greenhouse gases equal to the emissions of more than 10 million cars.”
Since lighting accounts for 20 to 25 percent of U.S. energy consumption, the move to more energy efficient lighting is very important.
Types of Lighting
There are three primary uses, or functions, for lighting in homes: task, ambient, and accent. Task lighting provides light to perform work. Ambient lighting may include light that is used for work but also includes lighting for safety and security. Any lighting used for contrast or ambiance is accent lighting. There are many different types of artificial lights available for residential uses.

The document discusses three main options for energy-efficient lighting: fluorescent lights, compact fluorescent lights (CFLs), and light-emitting diode (LED) lights. Fluorescent lights last much longer than incandescent bulbs and use less energy. CFLs are smaller than fluorescent tubes and can fit in standard light fixtures. LED lights have the longest lifespan, use the least amount of energy, and don't contain mercury like fluorescent bulbs. However, LEDs currently have higher upfront costs and produce lower quality light than other options.
Incandescent lamp
The document discusses the history and operation of incandescent light bulbs. It explains that in 1802, Humphry Davy demonstrated that running electricity through a thin metal strip could heat it enough to produce light. However, early light bulbs had short lifetimes due to filament burn up in air. Improvements were made to combat this, but generating electricity was costly. The document also describes how incandescent bulbs work, their availability in different sizes and voltages, their uses, and properties like color temperature.
LED Light Bulbs
LED light bulbs are becoming more popular replacements for traditional incandescent and fluorescent bulbs due to their efficiency, durability and safety. They use significantly less power than other bulbs, last longer, and produce less heat. LED bulbs come in a variety of shapes, sizes and colors for both indoor and outdoor use, such as decorative bulbs, floodlights and spotlights. While LEDs have a higher initial cost, this is offset by their long lifespan and lower long-term energy costs compared to other bulb types. Proper selection of an LED bulb depends on its intended use and factors like light output, power needs, and compatibility with fixtures.

Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

Other Types of Lamps.pptx
- 1. Other Types of Lamps
- 2. Halogen bulbs are often found in homes as spotlights or floodlights, in cars as headlights, or at sports fields as stadium lights. These bulbs work in a similar way to an incandescent bulb by running electricity through a tungsten filament. Unlike the incandescent, there is halogen gas inside the bulb. When the tungsten burns off the filament, the gas re-deposits it back onto the filament to be reused. Halogen bulbs last much longer than incandescent, but these bulbs are much brighter and burn much hotter than traditional incandescent bulbs. Halogen Bulbs:
- 3. Metal Halide Metal halide lamps are commonly used in streetlights, parking lot lights, and stadium lights. They are very bright and contribute to a lot of light pollution. They are fairly efficient. They produce very white light and have good color rendition, meaning that objects under these lights look their true color.
- 4. High Pressure Sodium (HPS): The high pressure sodium lamp (HPS) is the most commonly used street light throughout the world. It produces light by running electricity through a mixture of gases, which produces light. The lamp itself is preferred because it requires little maintenance. These lamps are fairly efficient. They take a while to turn on completely and produce a yellow-orange glow.
- 5. Neon lamps are gas discharge lamps that contain neon gas at a low pressure, enveloped in a glass capsule. Gas discharge lamps emit light when electric light is passed through the gas. Neon lamps have been used widely in neon sign boards. They provide a distinct orange glow. Commonly use in architectural design. Neon lamps
